I'm pretty interested in knowing this too. My plane, the CRJ, has one of the fastest approach speeds out there of airliners. We'll cross the fence at up to 147kts (170mph) in normal situations and go all the way up to about 183kts (210mph) in abnormal situations (such as a flaps failure or overweight landing... both of which happens reasonably often).

Doesn't exactly qualify as a "fighter" per se, but all fighter guys have flown it for training -- if I'm not mistaken the T-38 Talon moves pretty quick on final. Also, I've heard the pilot has to do some additional fuel weight calculations to determine the appropriate final approach speed.
Maybe those with experience in the T-38 can verify?

Had to check an old reference (it's been close to 20 years since I flew the White Rocket...) Final approach speed was 155kts + 1 kt per 100 lbs of fuel over 1000 lbs. Touchdown was 130kts + fuel adjustment. Full fuel was just under 4000 lbs, and I don't recall many landings with more than 1000 lbs left.

Regarding the T-38 (A-model), Vso with 100% flaps ranged from 120 KIAS at the very lightest weights to 144 KIAS at heavier landing weights. Using 1.3 Vso to determine Vapp, that puts Vapp anywhere from 156 KIAS to 187 KIAS.
With no flaps, Vso ranged from 126 KIAS at the lightest weights to 162 KIAS at heavier landing weights. Again, using the 1.3 Vso rule, that puts the zero-flap Vapp anywhere from 164 KIAS to 211 KIAS.
I found the following reference to the F-104 on another board:
No flap speed was 230 kts or 2.5 APC (AOA) whichever was higher, min touch down speed 190 kts.
Very difficult thing to do.......the limit for the chute was 180 kts and the brakes were real crap :yuk:.....very good chance to engage the bliss back barrier...
If for real, you had to eject all the external loads (except tip tanks) and burn the fuel down to 3,500 lbs. Tip tanks actually helped a lot in keeping induced drag under control.
Normal landing speed with full flaps was 175 kts + fuel correction ~ 5 kts for each 1,000 lbs above 1,000 lbs*....usually 185-190 kts, min touch down speed 150 kts....other difficult thing to do...
*I'm not 100% sure though....my last flight on the 104 dates back in 1995.
High key, for training, at 27,000', 260 kts, flaps TO and speedbrake out to simulate the open nozzles....gear down over the numbers or earlier if too high.
p.s. the above speeds are tipical of the S model...

The T-38's are sailing on approach..there's hardly any wing on that plane, and it's so damn clean that slowing it down is a beast.
Not that it's approach speed, but those old A-7's used to take up the whole runway on rollout- it approached in the 140's, but would use the whole strip to stop without blowing the tires- not much braking power and the speedbrake was mounted on the belly

I think there is a Guinness Book entry for the highest achieved landing speed, stating that a German F104 which had become damaged had to land extremely fast. Of course, that was not a regular approach, but the F104 certainly is among the fastest ones for normal approaches, as well.

The Tornado has an approach speed of 210 knots if the wings have an actuator failure and they are stuck in the "swept back" position. A serious option (as it is right on the limit of tyre burst speeds) is to eject. The undercarriage is a bit "gangley"...
